True - but not in the big picture.  If there's enough breakpoints that
walking the linked list checking ->inserted is a problem, think how
much more of a problem removing them and inserting them every step time
must be.  The nice thing about keeping it private in infrun.c is no one
else will use it...

I don't think we're going to be able to keep being so cavalier with
removing and reinserting breakpoints.
